Show HN: QR Code Editor with static and dynamic QR codes (client-side first)

https://qrcodeeditor.com/
1•assetofbaskets•1h ago
Hi HN,

I built a small QR code editor after repeatedly running into the same problem: once a QR code is printed, the destination is frozen.

This tool supports both:

Static QR codes (generated entirely client-side)

Dynamic QR codes (editable destination after creation)

Dynamic QR codes come with a minimal dashboard where you can:

Update the QR destination without reprinting

See basic scan stats (count, device, time, approximate origin)

I intentionally kept the feature set small and avoided heavy analytics or tracking. The goal is something simple that works well for menus, flyers, events, and small businesses.

The app is live here: https://qrcodeeditor.com/

I’d appreciate feedback on:

What’s missing for this to be useful day-to-day

Whether dynamic QR codes are something you actually need

What you’d expect before paying for a tool like this

Thanks for reading.
